I watch this because my friends said that this is really awesome so I decided to watch this. At first I don't want to watch this because this is historical drama and my favorite type is RomCom so this is something new for me. I thought this will be like boring and dramatic love stories but it's actually not boring and really sweet also cute and pure. I really don't regret watching this. In fact, I personally think this drama is really great. The story is really great and unique. I love how the story and twist develop in each episodes too. Although on some parts [especially on some first episode] is not really good and boring but it's getting better and better and the ending is definitely not disappointing ! The cast is AWESOME. I all love the teen actors and the adult actors. Both are awesome. And surprisingly I actually think that the teen and adult faces resemble each other so it's really convenient ^^ Overall I think this drama is really worth watching and I suggest everyone to watch this.
